MECHAIiTICAL MOVEMENT.

Application filed June 6, 1919.

To all whom it may concern:

Be it known that I Grim-nun) MiiLLnn, a citizen of Germany, having declared my intention to become a citizen of the United States, residing in the city of New 81 01115 Glendale, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Mechanical Movement, of which the following is a full, clear, and exact description.

The invention relates to mechanism for converting reciprocating motion into intermittent rotary motion. and its object 'is to provide a new and improved mechanical movement more especially designed'for intermittent feeding purposes and which is simple and durable in'construction and composed of comparatively few parts, not liable the get easily out of order. Another object is to reduce the wear of the working parts to a minimum and to insure proper functioning of the parts without danger of binding or sticking.

With these and other objects in view, the invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the mechanical movement With parts broken out and parts shown in section; V

Fig. 2 is a transverse view of the same on the line 2 2 of Fig. 1;

Fig. 3 is a side elevation of part of the mechanical movement and showing the clamping member in clamping position on the driven Wheel;

Fig. 4 is a perspective of the clamping or Wedging member;

Fig. 5 is a side elevation of a modified form of the improved mechanical movement with part of the carrier shown in section;

Fig. 6 is a side elevation of the same with the clamping member in clamping position; and Fig. 7 is a perspective view of the clamping or Wedging member shown in Figs. 5 and 6.

A reciprocating rack 10 is in mesh with a gear wheel 11 having its hub 12 mounted to turn on a stud 13 attached to the frame Specification of Letters Patent. Patgnfiyf A 13 192(1 Serial No. 302,187.

of the machine on which the mechanical movement is used for intermittent feeding or s milar purposes. On the hub 12 is keyed or otherwise fastened a carrier 15.

mately at a right angle to the bottom 26 which latter forms a portion of a chord. The side wall 27 is disposed slightly out of radial alinement. In the cut-out portion 25 is mounted a clamping or wcdging member 30 having a roughened peripheral face 31 adapted to engage the inner surface of the driven wheel 16. The bottom of the clamping or wedging member 30-is provided with a lug 82 slidably engaging the bottom 26 of the cut-out portion 25, and the side 33 of the clamping or wedging member 30 is pressed on by a spring 3 L seated in a recess 35 formed in the side wall 27 of the cut-out portion 25; The axis of'the spring 35 is approximately parallel with the bottom 26 of the cut-out portion and at a right angle to the side 33 of the clamping or wedging member 30. By this arrangement the peripheral face 31 of the clamping or wedging member 30 is pressed in contact with the inner face of the driven wheel 16 and hence when the carrier 15 rotates in the direction of the arrow m, shown in Fig. 1, then the peripheral face 81 of the clamping member 30 glides over the inner face of the driven wheel 16 Without rotating the latter. hen the carrier 15 however, is rotated in the op posite direction, that is, in the direction of the arrow y, shown in Fig. 3, then the bottom 26 of the cut-out portion 25.pressing against the lug 32 forces the peripheral face of the clamping or wedging member 30 into firm clamping contact with the inner surface of the driven wheel 16 thus rotating the same in the direction of the arrow 3 It is understood that the lug 32 practically forms a fulcrum for the clamping or wedging member to rock on to engage or disengage the scribed.

15 is turned at the time.

It'is understood that when the rack 10 is on the 'return'stroke, that is, moves in the direction of the arrow 2, shown in Fig. 1, then the carrier 15 is rotated in the direction of the arrow as and the driven wheel 16 remains at a standstill, but when the rack 10 is moved in the inverse direction of the arrow 2 then the carrier 15 is turned in the direction of the arrow 3 (see Fig. 3) and the driven wheel 16 is carried along in this direction, as above explained.

Instead of the lug 32 engaging the bottom 26, use may be made of a rocking link 40 approximately in the shape of a figure eight, seated at one end in a recess 41 formed in the underside of the clamping or wedging block 42, similar in other respects to the clamping or wedging block 30 above de- The lower end of this link 40 is seated in a seat 43 formed in a carrier 44: corresponding to the carrier 15.

The action of the device disclosed in the modified. form shown in Figs. 5 and 6 is the same as above described in reference to preferably vmade of hardened steel to reduce the wear to a minimum.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A mechanical movement for converting reciprocating movement into intermittent rotary movement, comprising a driving wheel rotated alternately in opposite directions, a driven wheel, a carrier rotating with the said driven wheel and on which the said driven wheel is mounted to turn, the said carrier having a cut-out portion at its peripheral face, the bottom of the cut-out portion forming a portion of a chord, and the side wall of the cut-out portion bein approximately at a right angle to the said bottom, and a spring-pressed clamping member mounted to slide and rock in the said cut-out portion and having a roughened segmental peripheral face adapted to engage the inner face of the said driven wheel.

2. A mechanical movement for converting reciprocating movement into intermittent rotary movement, comprising a driving wheel rotated alternately in opposite directions, a driven wheel, a carrier rotating with the said driving wheel and on which the said driven wheel is mounted to turn, the said carrier having a cut-out portion at its peripheral face, the bottom of the out out portion forming a portion of a chord and the side wall of the cut-out portion being approximately at a right angle to the said bottom, a slidable and rockable clamping member arranged in the said cut-out portion and having a pivot at its bottom, the said clamping member having a roughened segmental face engaging the inner face of the said driven wheel, and a spring interposed between the said clamping member and the said side wall of the carrier.

3. A mechanical movement for converting reciprocating movement into intermittent rotary movement, comprising a driving wheel rotated alternately in opposite directions, a driven wheel, a carrier rotating with the driven wheel and. on which the driven wheel is mounted to turn, the carrier having a cut-out portion the bottom and end wall of which are approximately at right angles, the bottom and end wall each having a recess, a clamping member in the cut-out portion of the carrier and having a segmental face and a recess in its lower face, a link engaging the recess of the carrier and the recess in the lower face of the clamping member, and a spring in the recess of the end wall of the cut-out portion of the carrier and engaging the clamping member.
